Carlschoenherria adoradae Calcetas , new species

(Figs. 1–4, 36)

Type locality. The Philippines, Luzon Island , Kalinga Apayao .

Type material. Holotype (male), labeled: Apayao, Bayog , Elev. 300 ft., 15-v-1952, S.M. Cendana ( MNH).

Description of holotype, male. Length 20.5 mm, width 8.5 mm. Body dichromatic, head, pronotum and scu- tellum dark reddish brown; uniformly covered with short, brownish to whitish setae; elytron light reddish brown, covered with short brownish to yellowish setae, with few short whitish acicular-like scales; leg black (Fig. 1).

Head. Mesal carina starting at junction of fronto-clypeal suture, terminating far behind vertex. Anterior margin of clypeus straight dorsally; surface subrugosely punctate anteriorly; with very narrow, smooth margin, impunctate, non-setose area adjacent to anterior margin; dorsal surface of clypeus sloping, deeply depressed adjacent to anterior margin. Antennomere III with short stalk, widely expanded apically. Lamellae length 2.3 mm. Terminal maxillary palpomere with shallow nearly flattened lanceolate shaped groove or depression, as long as antennomere III. Men- tum with distinct roof-like mesal carina, slanted on each side, with deep depression below it; surface subrugosely punctate, covered with few setae and acicular-like scales.

Ventral side of thorax. Prosternal process rectangulate, elongate, slender or narrow longitudinally, truncate apically. Prosternum and mesoventrum densely covered with long yellowish hairs. Metaventral process little prolonged, not reaching procoxae, sub-apically attached to mesoventral process; metaventral process length 1.5 mm.

Abdominal ventrites not uniformly covered with setation, bare at least near each margin or rather narrowly restricted in distribution of setation; posterior part of abdominal ventrites II–IV narrow, smooth, bare; sides of II–V with large and small ovoid shaped patches of yellowish-white scales or abdominal maculation.

Pygidium with anterior margin nearly straight; posterior margin wide.

Aedeagus. Posterior margin of parameres ribbon-like, longitudinally undulated towards apex. Length of param- eres and phallobase combined 6.4 mm; as in Figs. 3, 4.

Distribution. The Philippines (Luzon).

Etymology. This new species is named after Dr. Jessamyn R. Adorada, professor of taxonomy and systematics at the University of the Philippines, Los Baños. She is also an expert on Philippine coccinellids.

Differential diagnosis. Based on the species-group classification of Itoh (1993), this species belongs to the C. sulcipennis group wherein the parameres are laterally compressed and bird-bill shaped at apex. However, in contrast to other members of C. sulcipennis group, the anterior margin of the parameres of C. adoradae Calcetas , new species and C. hadsallae Calcetas , new species are wide and laterally expanded while it’s laterally compressed and bird-bill shaped at apex for all other species. Thus, they are classified under the newly proposed C. adoradae species-subgroup.
